Definitions
- the present disclosure relates to a system for avoiding a blind spot of a vehicle using accident history information and a method thereof, and more particularly to a system for avoiding a blind spot of a vehicle using accident history information, capable of determining a dangerous level of a blind spot of a large vehicle, and reflecting the dangerous level to a traveling path of a host vehicle, thereby preventing an accident from occurring due to the blind spot of the large vehicle, and a method thereof.
- a driver has to determine a traffic situation during driving of a vehicle and to drive the vehicle.
- the driver has to drive the vehicle by appropriately detecting a surrounding vehicle.
- the driver may sense only a limit area due to the structural limitation of the vehicle.
- the limit area refers to a side area, which is sensed by the driver through a side view mirror, and a blind spot, which is sensed as the driver turns the head of the driver and is an area other than the side area.
- BSD blind spot detection
- a next-lane vehicle which is not equipped with the BSD system and positioned on a next lane, may still change the lane while failing to recognize the host vehicle positioned in a blind spot of the next-lane vehicle, and the host vehicle has to avoid the blind spot and travel.
- a system for avoiding a blind spot using accident history information includes an image sensor configured to provide image information by acquiring a surrounding image of a host vehicle, and a vehicle controller.
- the vehicle controller is configured to detect, through the image sensor, an adjacent vehicle traveling adjacent to the host vehicle and a license plate of the adjacent vehicle; determine a dangerous level of the blind spot of the adjacent vehicle, based on accident history information of the adjacent vehicle and driver tendency information of a driver of the adjacent vehicle obtained by inquiring about the license plate of the adjacent vehicle, after determining a blind spot range of the adjacent vehicle; and generate a path in which the host vehicle deviates from the blind spot or avoids the blind spot to reduce the dangerous level of the blind spot, based on a traveling situation of the host vehicle.
- the vehicle controller may include a blind spot range generator configured to detect the adjacent vehicle traveling adjacent to the host vehicle, based on the image information received through the image sensor, and determine a default blind spot range; a traveling road information generator configured to provide, as traveling road information, information on a road on which the host vehicle is travelling, based on the image information; a blind spot range changing device configured to change the default blind spot range, based on the traveling road information; a blind spot dangerous level determining device configured to determine the dangerous level of the blind spot by matching a dangerous level of the adjacent vehicle, deduced by analyzing the accident history information of the adjacent vehicle and the driver tendency information of the driver of the adjacent vehicle, with the default blind spot range changed based on the traveling road information; and a path generator configured to generate the path for minimizing the dangerous level of the blind spot, based on the traveling situation of the host vehicle and to longitudinally or laterally control the host vehicle.
- a traveling road information generator configured to provide, as traveling road information, information on a road on which the host vehicle is travelling, based on the image
- the blind spot range generator may include an object type determining device configured to determine a type of the adjacent vehicle, based on the image information; an object size determining device configured to calculate a size of the adjacent vehicle, based on the image information; a host vehicle information storage configured to store data of the host vehicle, including a total height of the host vehicle and a roof area of the host vehicle; and a blind spot range determining device configured to determine the default blind spot range, based on any one or any combination of any two or more of the type of the adjacent vehicle, the size of the adjacent vehicle, the total height of the host vehicle, and the roof area of the host vehicle.
- the blind spot range determining device may select one of blind spots stored depending on types of adjacent vehicles, based on the determined type of the adjacent vehicle; match the selected blind spot with the detected adjacent vehicle; and determine the blind spot range matched with the adjacent vehicle, based on any one or any combination of any two or more of the determined size of the adjacent vehicle, the total height of the host vehicle, and the roof area of the host vehicle to determine the default blind spot range.
- the blind spot dangerous level determining device may determine the dangerous level of the blind spot by matching the dangerous level of the adjacent vehicle, deduced by using the accident history information, including a number of times of accidents, an accident type, and an accident scale, of the adjacent vehicle, and the driver tendency information of the driver of the adjacent vehicle received from an information providing server, with the default blind spot range changed based on a traveling path of the host vehicle and a traveling path of the adjacent vehicle.
- the vehicle controller may be further configured to accelerate the host vehicle to deviate the host vehicle from the blind spot range, when the dangerous level of the blind spot and the dangerous level of the adjacent vehicle are higher than a specific reference, and when the host vehicle travels within the blind spot range of the adjacent vehicle.
- the vehicle controller may be further configured to generate a path of passing through a safer blind spot by determining the dangerous level of the blind spot and the dangerous level of the adjacent vehicle, when the host vehicle avoids the blind spot of the adjacent vehicle by passing through the blind spot of the adjacent vehicle.
- the adjacent vehicle may be larger than the host vehicle.
- the adjacent vehicle may be a truck or a bus.
- a method for avoiding a blind spot using accident history information includes providing image information by acquiring a surrounding image of a host vehicle through an image sensor; detecting, by a vehicle controller, an adjacent vehicle traveling adjacent to the host vehicle and a license plate of the adjacent vehicle; determining a dangerous level of the blind spot, based on accident history information of the adjacent vehicle and driver tendency information of a driver of the adjacent vehicle obtained by inquiring about the license plate of the adjacent vehicle, after determining a blind spot range of the adjacent vehicle; and generating a path in which the host vehicle deviates from the blind spot or avoids the blind spot to reduce the dangerous level of the blind spot, based on a traveling situation of the host vehicle.
- the detecting, by the vehicle controller, of the adjacent vehicle may include detecting, by a blind spot range generator, the adjacent vehicle traveling adjacent to the host vehicle, based on the image information received through the image sensor, and determining a default blind spot range of the adjacent vehicle; and providing, by a traveling road information generator, as traveling road information, information on a road on which the host vehicle is travelling, based on the image information.
- the determining of the dangerous level of the blind spot may include changing, by a blind spot range changing device, the default blind spot range, based on the traveling road information; and determining, by a blind spot dangerous level determining device, the dangerous level of the blind spot by matching a dangerous level of the adjacent vehicle, deduced by analyzing the accident history information of the adjacent vehicle and the driver tendency information of the driver of the adjacent vehicle, with the default blind spot range changed based on the traveling road information.
- the generating of the path in which the host vehicle deviates may include generating, by a path generator, a path for minimizing the dangerous level of the blind spot, based on the traveling situation of the host vehicle; and longitudinally or laterally controlling the host vehicle.
- the determining of the dangerous level of the blind spot may include determining, by an object type determining device, a type of the adjacent vehicle, based on the image information; calculating, by an object size determining device, a size of the adjacent vehicle, based on the image information; storing, by a host vehicle information storage, data of the host vehicle, including a total height of the host vehicle and a roof area of the host vehicle; and determining, by a blind spot range determining device, the default blind spot range, based on any one or any combination of any two or more of the type of the adjacent vehicle, the size of the adjacent vehicle, the total height of the host vehicle, and the roof area of the host vehicle.
- the determining of the dangerous level of the blind spot may include selecting one of blind spots stored depending on types of adjacent vehicles, based on the determined type of the adjacent vehicle; matching the selected blind spot with the detected adjacent vehicle; and determining a blind spot range matched with the adjacent vehicle, based on any one or any combination of any two or more of the determined size of the adjacent vehicle, the total height of the host vehicle, and the roof area of the host vehicle to determine the default blind spot range.
- the determining of the dangerous level of the blind spot may include determining the dangerous level of the blind spot by matching the dangerous level of the adjacent vehicle, deduced by using the accident history information, including a number of times of accidents, an accident type, and an accident scale, of the adjacent vehicle, and the driver tendency information of the driver of the adjacent vehicle, received from an information providing server, with the default blind spot range changed based on a traveling path of the host vehicle and a traveling path of the adjacent vehicle.
- the generating of the path in which the host vehicle deviates may include accelerating the host vehicle to deviate the host vehicle from the blind spot range of the adjacent vehicle, when the dangerous level of the blind spot and the dangerous level of the adjacent vehicle are higher than a specific reference, and when the host vehicle travels within the blind spot range of the adjacent vehicle.
- the generating of the path in which the host vehicle deviates may include generating a path of passing through a safer blind spot by determining the dangerous level of the blind spot and the dangerous level of the adjacent vehicle, when the host vehicle avoids the blind spot of the adjacent vehicle by passing through the blind spot of the adjacent vehicle.

Abstract
Description
- This application claims the benefit under 35 USC 119(a) of Korean Patent Application No. 10-2020-0074241, filed in the Korean Intellectual Property Office on Jun. 18, 2020, the entire disclosure of which is incorporated herein by reference for all purposes.
- The present disclosure relates to a system for avoiding a blind spot of a vehicle using accident history information and a method thereof, and more particularly to a system for avoiding a blind spot of a vehicle using accident history information, capable of determining a dangerous level of a blind spot of a large vehicle, and reflecting the dangerous level to a traveling path of a host vehicle, thereby preventing an accident from occurring due to the blind spot of the large vehicle, and a method thereof.
- In general, a driver has to determine a traffic situation during driving of a vehicle and to drive the vehicle. In particular, the driver has to drive the vehicle by appropriately detecting a surrounding vehicle.
- However, the driver may sense only a limit area due to the structural limitation of the vehicle.
- The limit area refers to a side area, which is sensed by the driver through a side view mirror, and a blind spot, which is sensed as the driver turns the head of the driver and is an area other than the side area.
- Although a blind spot detection (BSD) system has been developed such that the driver recognizes the blind spot through a sensor, all vehicles are not equipped with the BSD system.
- Accordingly, although a host vehicle is equipped with the BSD system, a next-lane vehicle, which is not equipped with the BSD system and positioned on a next lane, may still change the lane while failing to recognize the host vehicle positioned in a blind spot of the next-lane vehicle, and the host vehicle has to avoid the blind spot and travel.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

FIGS. 1 and 2 , according to an embodiment of the present disclosure, a system for avoiding the blind spot of the vehicle using accident history information may include ahost vehicle 100 including asensor 110, animage sensor 130, avehicle controller 200, adisplay 300, aspeed controller 500, and acommunication device 700. - The
sensor 110 may include a radar, a Light Detection and Ranging (LiDAR), and an ultrasonic sensor mounted on a side surface of thehost vehicle 100, may sense a next-lane vehicle traveling on a lane next to a lane of thehost vehicle 100, and may provide information on the next-lane vehicle to thevehicle controller 200. - The
image sensor 130 may include at least one of a front camera to acquire a front image of thehost vehicle 100, a rear camera to acquire a rear image of thehost vehicle 100, a left camera to acquire a left image of thehost vehicle 100, or a right camera to acquire a right image of thehost vehicle 100. Theimage sensor 130 may acquire a surrounding image of thehost vehicle 100, may generate image information, and may provide the generated image information to thevehicle controller 200. - For example, the
image sensor 130 may acquire the front image, the rear image, the left image, and the right image of thehost vehicle 100, and may provide the acquired image, which serves as the image information, to a blindspot range generator 210 and a travelingroad information generator 230 of thevehicle controller 200. - The
image sensor 130 may sense a license plate of alarge vehicle 50, which is positioned around thehost vehicle 100, and may provide information on the license plate to thevehicle controller 200. - The
vehicle controller 200 may receive information (accident history information) on an accident history of thelarge vehicle 50 and information on the tendency of a driver, which are obtained from the inquiry of the license plate, from aninformation providing server 900, after transmitting the information on the license plate, which is sensed through theimage sensor 130, of thelarge vehicle 50 to theinformation providing server 900 and may reflect the information in determining a dangerous level of a blind spot. Thevehicle controller 200 may include the blindspot range generator 210, the travelingroad information generator 230, a blind spotrange changing device 250, a blind spot dangerous level determining device 270, and apath generator 290. - The blind
spot range generator 210 may receive, as the image information, the sensing result of thesensor 110 and a surrounding image, which is acquired from theimage sensor 130, of thehost vehicle 100. The blindspot range generator 210 may determine a default blind spot range of thelarge vehicle 50 traveling around thehost vehicle 100, based on the image information. - In this case, the blind
spot range generator 210 may provide, as default blind spot range information, the determined default blind spot range of thelarge vehicle 50 to the blind spotrange changing device 250. - For example, the blind
spot range generator 210 may sense thelarge vehicle 50 positioned around thehost vehicle 100, based on the image information, may determine the type and the size of thelarge vehicle 50, may determine the default blind spot range of thelarge vehicle 50 traveling around thehost vehicle 100, based on the type and the size of thelarge vehicle 50 and the information of thehost vehicle 100, and may provide, as the default blind spot range information, the default blind spot range of thelarge vehicle 50 to the blind spotrange changing device 250. - In addition, referring to
FIG. 3 , the blindspot range generator 210 may include an objecttype determining device 211, an objectsize determining device 213, a hostvehicle information storage 215, and a blind spotrange determining device 217. - The object
type determining device 211 may determine the type of a vehicle traveling adjacent to thehost vehicle 100, based on the image information, and may provide, as determined object type information, the determined information to the objectsize determining device 213 and the blind spotrange determining device 217. - For example, when the vehicle traveling adjacent to the
host vehicle 100 is determined as being thelarge vehicle 50, based on the image information, the objecttype determining device 211 may insert the information on that the vehicle traveling adjacent to thehost vehicle 100 is thelarge vehicle 50, and information on the type of thelarge vehicle 50 into determined object type information, and may provide the inserting result to the objectsize determining device 213 and the blind spotrange determining device 217. - In this case, the type of the
large vehicle 50 may include a truck or a bus. - The object
size determining device 213 may calculate the size of thelarge vehicle 50, based on the image information, and provide, as object size information, the calculated information to the blind spotrange determining device 217, when the information on that the vehicle traveling adjacent to thehost vehicle 100 is thelarge vehicle 50 is inserted into the determined object type information provided from the objecttype determining device 211. - For example, the object
size determining device 213 may calculate the total height and the width of thelarge vehicle 50, based on the image information, and provide, as the object size information, the calculated information to the blind spotrange determining device 217, when receiving the information on that the vehicle traveling adjacent to thehost vehicle 100 is thelarge vehicle 50 and the information on the type of thelarge vehicle 50. - The host
vehicle information storage 215 may store information (such as the total height and the width of thehost vehicle 100, and an area of a main portion (for example, a roof area of the vehicle or an area between an A pillar and a C pillar) forming the total height of the host vehicle 100) of thehost vehicle 100, and may provide, as information (host vehicle information) on thehost vehicle 100, the stored information to the blind spotrange determining device 217. - The blind spot
range determining device 217 may receive the determined object type information from the objecttype determining device 211, receive the object size information from the objectsize determining device 213, and receive the information on the host vehicle from the hostvehicle information storage 215. - The blind spot
range determining device 217 may generate the default blind spot range information, based on at least one of the determined object type information, the object size information, and the host vehicle information. - For example, the blind spot
range determining device 217 may determine the default blind spot range of thelarge vehicle 50 traveling adjacent to thehost vehicle 100, based on the type of thelarge vehicle 50, which is included in the determined object type information, the size of thelarge vehicle 50, which is included in the object size information, and the total height of thehost vehicle 100 and the roof area of thehost vehicle 100 which are included in the information on thehost vehicle 100, and may output, as the default blind spot range information, the determined default blind spot range. - In other words, the blind spot
range determining device 217 may select one of blind spots stored depending on types oflarge vehicles 50, based on the determined type of thelarge vehicle 50, may match the selected blind spot with the sensedlarge vehicle 50, and may determine the blind spot range matched with thelarge vehicle 50, based on the determined size of thelarge vehicle 50 and the total height and the roof area of thehost vehicle 100, thereby determining the default blind spot range. - The traveling
road information generator 230 may receive, as the image information, the surrounding image, which is acquired from theimage sensor 130, of thehost vehicle 100, may generate information on a road (traveling road of the host vehicle 100) on which thehost vehicle 100 travels, based on the image information, and may provide, as traveling road information, the generated road information to the blind spotrange changing device 250 and the blind spot dangerous level determining device 270. - For example, the traveling
road information generator 230 may determine a curvature, a lateral gradient, a longitudinal gradient, and a merging point of the travelling road of thehost vehicle 100, based on the image information, and may provide, as the traveling road information, the determined information to the blind spotrange changing device 250 and the blind spot dangerous level determining device 270. - The blind spot
range changing device 250 may receive the default blind spot range information provided from the blindspot range generator 210 and the traveling road information provided from the travelingroad information generator 230. - The blind spot
range changing device 250 may generate changed blind spot range information by changing the default blind spot range information, which is generated based on the image information, based on the traveling road information, and may provide the generated and changed blind spot range information to the blind spot dangerous level determining device 270. - For example, the blind spot
range changing device 250 may expand or reduce the blind spot range of thelarge vehicle 50, which is included in the default blind spot range information, based on at least one of information on a curvature, information on a lateral gradient, or information on a longitudinal gradient of the traveling road, which is included in the traveling road information, and may output the expanded or reduced result serving as the changed blind spot range information. - The blind spot dangerous level determining device 270 may match the dangerous level of the
large vehicle 50, which is deduced by analyzing the accident history information of thelarge vehicle 50 and the driving tendency information of the driver of thelarge vehicle 50, which are obtained from the inquiry of the license plate of thelarge vehicle 50, with the changed default blind spot range based on the traveling road information, and may output, as blind spot information, the information on the changed default blind spot range matched with the dangerous level of thelarge vehicle 50. - For example, the blind spot dangerous level determining device 270 may determine a dangerous ranking for blind spots of the
large vehicle 50 by matching the dangerous level of thelarge vehicle 50, which is obtained based on the accident history information, which includes the number of times of accidents, an accident type, and an accident scale received from theinformation providing server 900, of thelarge vehicle 50 and on the driving tendency information of the driver of thelarge vehicle 50, with the default blind spot range changed depending on the traveling path of thehost vehicle 100 and the traveling path of thelarge vehicle 50. - Thereafter, the blind spot dangerous level determining device 270 may output, as blind spot information, blind spot varying range information having the determined dangerous ranking.
- In other words, the blind spot dangerous level determining device 270 may determine the dangerous level of the
large vehicle 50 as being higher, as the number of times of accidents of thelarge vehicle 50, which is received from theinformation providing server 900, is increased. In addition, when the driver of thelarge vehicle 50 is determined as corresponding to a driver careless a front-right portion or at a front portion by using the driver tendency information of the driver of thelarge vehicle 50, which is obtained from theinformation providing server 900, the blind spot dangerous level determining device 270 may determine the blind spot positioned at the front-right portion or the front portion of thelarge vehicle 50 as a place having a higher dangerous level. - The
path generator 290 may generate a path to minimize the dangerous level, based on the traveling situation of thehost vehicle 100, and may longitudinally or laterally control for thehost vehicle 100 such that thehost vehicle 100 may travel while deviating from or avoiding the blind spot. - The
display 300 may include a sound device or a display device. Thedisplay 300 may link to a navigation device (not illustrated) to map a path (avoiding path) for avoiding the blind spot and a path (deviating path) for deviating from the blind spot to map data and may display the map data on a screen. - The
speed controller 500 may control thehost vehicle 100 to decelerate or accelerate on the traveling path, when thehost vehicle 100 fails to generate the path for deviating from the blind spot or the path for avoiding the blind spot to travel. - The
communication device 700, which wirelessly makes communication with theinformation providing server 900, may transmit, to theinformation providing server 900, the information on the license plate of thelarge vehicle 50, which is photographed through theimage sensor 130 of thehost vehicle 100, and may receive, from theinformation providing server 900, the number of times of accidents, the accident type, or the accident scale of thelarge vehicle 50, and the driving tendency information of the driver of thelarge vehicle 50, which are to be transmitted to thevehicle controller 200. - Hereinafter, an operation for the blind spot
range determining device 217 to generate the default blind spot range information, based on the determined object type information, object size information, and host vehicle information will be described with reference toFIGS. 4 to 6 . - The blind spot
range determining device 217 may have various types of blind spot information depending on the types of theblind spot 50. - The blind spot
range determining device 217 may select one of blind spot information stored depending on the types of thelarge vehicle 50, based on the determined object type information, and may match the selected blind spot information with the sensedlarge vehicle 50. - Referring to
FIG. 4 , when thelarge vehicle 50 is a truck, the blind spot of thelarge vehicle 50 may include a left blind spot “A” of thelarge vehicle 50, a right blind spot “B” of thelarge vehicle 50, a front-right blind spot “C” of thelarge vehicle 50, and a rear blind spot “D” of thelarge vehicle 50. - In this case, the blind spot of the
large vehicle 50, which is illustrated inFIG. 4 , is shown on the assumption that the driver seat of thelarge vehicle 50 is positioned at the left side. Accordingly, when the driver seat of thelarge vehicle 50 is positioned at the right side, the form of the blind spot of thelarge vehicle 50 may be changed. - The blind spot
range determining device 217 may expand or reduce the range (e.g., size) of the blind spot matched with thelarge vehicle 50, based on information on thehost vehicle 100. - For example, the blind spot
range determining device 217 may expand or reduce the blind spot range matched with thelarge vehicle 50, based on at least one of the total height of thehost vehicle 100 or the roof area of thehost vehicle 100, which are included in the information on thehost vehicle 100. - In more detail, the blind spot
range determining device 217 may expand the blind spot range matched with thelarge vehicle 50, as the total height of thehost vehicle 100, which is included in the information on thehost vehicle 100, is reduced. - Meanwhile, the blind spot
range determining device 217 may reduce the blind spot range matched with thelarge vehicle 50, as the total height of thehost vehicle 100, which is included in the information on thehost vehicle 100, is increased. - The blind spot
range determining device 217 should be configured to expand or reduce the blind spot range matched with thelarge vehicle 50, based on the total height of thehost vehicle 100, because the driver of thelarge vehicle 50 fails to sufficiently recognize thehost vehicle 100, as the total height of thehost vehicle 100 becomes lower, while being able to sufficiently recognize thehost vehicle 100, as the total height of thehost vehicle 100 becomes higher as illustrated in reference numeral “A)” ofFIG. 5 . - Meanwhile, the blind spot
range determining device 217 may reduce the blind spot range matched with thelarge vehicle 50, as the roof area of thehost vehicle 100, which is included in the information on thehost vehicle 100, is increased. - Meanwhile, the blind spot
range determining device 217 may expand the blind spot range matched with thelarge vehicle 50, as the roof area of thehost vehicle 100, which is included in the information on thehost vehicle 100, is reduced. - The blind spot
range determining device 217 should be configured to expand or reduce the blind spot range matched with thelarge vehicle 50, based on the roof area of thehost vehicle 100, because the driver of thelarge vehicle 50 fails to sufficiently recognize thehost vehicle 100, as the roof area of thehost vehicle 100 becomes narrower, while being able to sufficiently recognize thehost vehicle 100, as the roof area of thehost vehicle 100 becomes wider as illustrated in reference numeral “B)” ofFIG. 5 . - In other words, when the roof area of the
host vehicle 100 is wider, the driver of thelarge vehicle 50 may more easily recognize thehost vehicle 100, as compared to when the roof area of thehost vehicle 100 is narrower. Accordingly, the matched blind spot of thelarge vehicle 50 may be expanded or reduced based on the roof area of thehost vehicle 100, thereby ensuring the safety of thehost vehicle 100. - In addition, the blind spot
range determining device 217 may expand or reduce the blind spot range matched with thelarge vehicle 50, based on the total height of thelarge vehicle 50, which is included in the information on the object size. - For example, as illustrated in reference numeral “A)” of
FIG. 6 , the blind spotrange determining device 217 may expand the blind spot range matched with thelarge vehicle 50, as the total height of thelarge vehicle 50, which is included in the object size information, becomes higher. - For example, as illustrated in reference numeral “B)” of
FIG. 6 , the blind spotrange determining device 217 may reduce the blind spot range matched with thelarge vehicle 50, as the total height of thelarge vehicle 50, which is included in the object size information, becomes lower. - The blind spot
range determining device 217 should be configured to expand or reduce the blind spot range matched with thelarge vehicle 50, based on the total height of thelarge vehicle 50, because the driver of thelarge vehicle 50 having the higher total height fails to sufficiently recognize thehost vehicle 100 traveling adjacent to thelarge vehicle 50 while the driver of thelarge vehicle 50 having the lower total height sufficiently recognizes thehost vehicle 100 traveling adjacent to thelarge vehicle 50. - In other words, the driver of the
large vehicle 50 having the lower total height may more easily recognize thehost vehicle 100 traveling adjacent to thelarge vehicle 50, as compared with the driver of thelarge vehicle 50 having the higher total height. Accordingly, the safety of thehost vehicle 100 may be ensured by expanding or reducing the blind spot of thelarge vehicle 50 depending on the sensed total height of thelarge vehicle 50. - As described above, the blind spot
range changing device 250 ofFIG. 2 may change the default blind spot range information of thelarge vehicle 50, which is generated from the blindspot range generator 210, based on the traveling road information, and may output, as the changed blind spot range information of thelarge vehicle 50, the default blind spot range information of thelarge vehicle 50, which is changed. - For example, the blind spot
range changing device 250 may change the default blind spot range information of thelarge vehicle 50, based on the information on the curvature, the information on the lateral gradient, and the information on the longitudinal gradient included in the traveling road information of thehost vehicle 100, and may output, as the changed blind spot range information of thelarge vehicle 50, the default blind spot range information of thelarge vehicle 50, which is changed. - As illustrated in reference numeral “A)” of
FIG. 7 , the blind spotrange changing device 250 may expand a right blind spot range of thelarge vehicle 50 on a left turn road, based on the curvature of the traveling road of thehost vehicle 100, which is included in the traveling road information, and may insert information on the expanded right blind spot of thelarge vehicle 50 into the changed blind spot range. In this case, the blind spotrange changing device 250 may expand the right blind spot range of thelarge vehicle 50, as the curvature of the left turn road is increased. - Although not illustrated, the blind spot
range changing device 250 may expand a left blind spot range of thelarge vehicle 50 on a right turn road, based on the curvature of the traveling road of thehost vehicle 100, which is included in the traveling road information. - In this case, the blind spot
range changing device 250 may expand the left blind spot range of thelarge vehicle 50, as the curvature of the right turn road is increased. - As described above, the blind spot
range changing device 250 may expand or reduce the default blind spot range, which is included in the default blind spot range information of thelarge vehicle 50, based on the curvature of the road, and may output information on the expanded or reduced range as the changed blind spot range information of thelarge vehicle 50. - In addition, the blind spot
range changing device 250 may change the default blind spot range information of thelarge vehicle 50, based on the information on the longitudinal gradient of the travelling road included in the traveling road information, and may output, as the changed blind spot range information of thelarge vehicle 50, the default blind spot range information of thelarge vehicle 50 which is changed. - For example, as illustrated in reference numeral “B)” of
FIG. 7 , the blind spotrange changing device 250 may expand a front-right blind spot of thelarge vehicle 50, when thelarge vehicle 50 reaches a turning point of the longitudinal gradient included in the traveling road information. In this case, although reference numeral “B)” ofFIG. 7 illustrates that the front-right blind spot of thelarge vehicle 50 is expanded at the turning point of the longitudinal gradient, at which an uphill is switched to a downhill, the front-right blind spot of thelarge vehicle 50 may be reduced at a point at which the downhill is switched to the uphill. - Although illustrated in
FIG. 7 , the blind spotrange changing device 250 may expand and reduce the front-right blind spot of thelarge vehicle 50 at a turning point of the lateral gradient, based on information on the lateral gradient of the travelling road, which is included in the traveling road information. - As described above, the blind spot
range changing device 250 may expand or reduce the default blind spot range, which is included in the default blind spot range information of thelarge vehicle 50, at the turning point of the longitudinal gradient or the lateral gradient, and may output information on the expanded or reduced range as the changed blind spot range information of thelarge vehicle 50. - The blind spot dangerous level determining device 270 of
FIG. 2 may match the dangerous level with the blind spot of thelarge vehicle 50, which is included in the changed blind spot range information, based on the traveling road information, and may output the changed blind spot range information of thelarge vehicle 50, which is matched with the dangerous level, as blind spot information. - For example, when a merging point, at which the traveling road of the
host vehicle 100 is merged with another road, is included in the traveling road information, the blind spot dangerous level determining device 270 may determine the dangerous ranking with respect to the blind spot of thelarge vehicle 50, based on the traveling path of thelarge vehicle 50 and the traveling path of thehost vehicle 100, and may output the change blind spot range information having the determined dangerous ranking, as the blind spot information. - For example, as illustrated in
FIG. 8 , when viewed from the merging point included in the traveling road information and when thehost vehicle 100 is traveling at the right side of thelarge vehicle 50, the blind spot dangerous level determining device 270 may match a dangerous level, which is higher than that of the left blind spot, to the right blind spot of thelarge vehicle 50 and the changed blind spot range information of thelarge vehicle 50 having the matched dangerous level may be output as the blind spot information. - Meanwhile, although not disclosed in drawings, when viewed from the merging point included in the traveling road information and when the
host vehicle 100 is traveling at the left side of thelarge vehicle 50, the blind spot dangerous level determining device 270 may match a dangerous level, which is higher than that of the right blind spot, to the left blind spot of thelarge vehicle 100 and the change blind spot range information of thelarge vehicle 50 having the matched dangerous level may be output as the blind spot information. - In addition, the blind spot dangerous level determining device 270 may generate blind spot information by matching the highest dangerous level to a blind spot of the
large vehicle 50, in which thehost vehicle 100 is to be merged at the merging point, based on the traveling path of thehost vehicle 100 and the traveling path of thelarge vehicle 50. - The
vehicle controller 200 may accelerate thehost vehicle 100 such that thehost vehicle 100 deviates from the blind spot, when thehost vehicle 100 is determined as being traveling within the blind spot range of thelarge vehicle 50 based on the blind spot information of thelarge vehicle 50 and when the dangerous level of the blind spot and the dangerous level of thelarge vehicle 50 are higher than a specific reference. - For example, the
vehicle controller 200 may control thehost vehicle 100 to instantly accelerate and to deviate from the blind spot to minimize a time for traveling of thehost vehicle 100 in a blind spot, when thehost vehicle 100 is determined as being traveling in the blind spot of thelarge vehicle 50, and when the number of times of accidents of thelarge vehicle 50 is five times, and the driving tendency of the driver of thelarge vehicle 50 is determined as being careless at the right portion and the front-right portion, so the dangerous level of the relevant blind spot and the dangerous level of thelarge vehicle 50 are higher. - In addition, when the
host vehicle 100 generates the path (avoiding path) for avoiding the blind spot, thehost vehicle 100 may pass through the blind spot of thelarge vehicle 50. Even in this case, thevehicle controller 200 may determine the dangerous level of the blind spot and the dangerous level of thelarge vehicle 50 to select a path of passing through a safer blind spot for travelling. - For example, the
vehicle controller 200 may determine the dangerous level of the blind spot and the dangerous level of thelarge vehicle 50, and may control thehost vehicle 100 to select a path of passing through a left blind spot, which is safer, of thelarge vehicle 50 for traveling, when thehost vehicle 100 generates the avoiding path, when thehost vehicle 100 passes through a blind spot of thelarge vehicle 50, when the number of times of accidents of thelarge vehicle 50 is five times, and when the driving tendency of the driver of thelarge vehicle 50 is determined as being careless at the right portion and the front-right portion. - Hereinafter, a method for avoiding a blind spot of a vehicle using accident history information, according to another embodiment of the present disclosure will be described with reference to
FIGS. 11 and 12 .FIGS. 11 and 12 are flowcharts illustrating the method for avoiding the blind spot of the vehicle using the accident history information, according to an embodiment of the present disclosure. - The following description will be made on the assumption that the system for avoiding the blind spot of the vehicle using the accident history information as illustrated in
FIGS. 1 and 2 performs processes ofFIGS. 11 and 12 . - First, the
large vehicle 50 traveling adjacent to thehost vehicle 100 may be sensed through the image sensor 130 (S101), and the dangerous level may be determined after determining the blind spot range of the large vehicle 50 (S102) - Regarding the dangerous level of the blind spot, the information on the license plate, which is sensed through the
image sensor 130, of thelarge vehicle 50 is transmitted to the information providing server 900 (S201), and the dangerous level of the blind spot may be determined based on the accident history information of thelarge vehicle 50 and the driving tendency information of the driver of the large vehicle 50 (S202). - Thereafter, the
vehicle controller 200 may determine whether the dangerous level of the blind spot is higher than specific reference to be reflected in generating a path, or is lower than the specific reference not to be reflected in generating the path (S203). - Thereafter, when the number of times of accidents of the
large vehicle 50 is five times, and when the driving tendency of the driver of thelarge vehicle 50 shows the carelessness at the front-right portion or the right portion, so the dangerous level of the blind spot is higher than the specific reference, the dangerous level of the blind spot may be reflected in generating the deviation path and an avoiding path (S204). When the dangerous level of the blind spot is lower than the specific reference, the dangerous level of the blind spot is not reflected in generating the deviating path and the avoiding path (S205). - Thereafter, the
vehicle controller 200 may determine whether thehost vehicle 100 is present in the blind spot of the large vehicle 50 (S103), and whether the path of deviating from the blind spot is generated (S104), and when the generation of the path of deviating from the blind spot is possible, thevehicle controller 200 may control thehost vehicle 100 to accelerate or decelerate or to change a lane to a next lane, such that thehost vehicle 100 deviates from the blind spot of the large vehicle 50 (S105). - In this case, when the
host vehicle 100 travels within the blind spot of thelarge vehicle 50 and when the dangerous level of the blind spot and the dangerous level of thelarge vehicle 50 are higher than THE specific reference, thehost vehicle 100 may instantly accelerate to rapidly deviate from the blind spot range. - Thereafter, when the
host vehicle 100 is scheduled to enter the blind spot of the large vehicle 50 (S107),vehicle controller 200 determines whether the path of avoiding the blind spot is generated (S108). When the path of avoiding the blind spot is generated,vehicle controller 200 may control thehost vehicle 100 to accelerate or decelerate or to change a lane to a next lane, such that thehost vehicle 100 deviates from the blind spot of the large vehicle 50 (S109). - In this case, when the
host vehicle 100 avoids the blind spot of thelarge vehicle 50 by passing through the blind spot of thelarge vehicle 50,vehicle controller 200 may determine the dangerous level of the blind spot and the dangerous level of thelarge vehicle 50 and may generate a path of passing through a safer blind spot. - Meanwhile, when the
host vehicle 100 does not enter the blind spot or when the path of avoiding the blind spot is failed,vehicle controller 200 may control thehost vehicle 100 to currently maintain an inter-vehicle distance to thelarge vehicle 50 and maintain a current lane (S110). - As described above, according to the present disclosure, the license plate of the large vehicle adjacently traveling may be inquired to analyze the accident history (the number of times of accidents, the type of the accident, or the scale of the accident), and the dangerous level of the large vehicle and the accident tendency of the driver may be deduced based on the analyzing result such that the dangerous level of the large vehicle and the accident tendency of the driver are reflected in generating the path of deviating from the blind spot and the path of avoiding the blind spot. Especially, the blind spot, which is formed by the large vehicle having the higher probability (the higher dangerous level) for the accident, may be more actively addressed (in terms of generating a path and controlling).
- Accordingly, the safe traveling of the host vehicle may be ensured by minimizing the traveling time in the blind spot of the large vehicle traveling adjacent to the host vehicle and the dangerous level. Accordingly, the driver of the host vehicle may feel psychological safety. In addition, the collision between a general sedan (smaller sedan) and a large vehicle may be reduced and thus the death rate from a traffic accident may be reduced, thereby preventing a large-scale accident resulting from the accident with the large vehicle.
- Hereinabove, although the present disclosure has been described with reference to exemplary embodiments and the accompanying drawings, the present disclosure is not limited thereto, but may be variously modified and altered by those skilled in the art to which the present disclosure pertains without departing from the spirit and scope of the present disclosure claimed in the following claims.
- Therefore, the exemplary embodiments of the present disclosure are provided to explain the spirit and scope of the present disclosure, but not to limit them, so that the spirit and scope of the present disclosure is not limited by the embodiments. The scope of the present disclosure should be construed on the basis of the accompanying claims, and all the technical ideas within the scope equivalent to the claims should be included in the scope of the present disclosure.
